In fact, we know plenty of on-again, off-again iPhone users who comfortably switch from Android to iOS and back again, and maybe some new Windows 10 fans who may even want to take the plunge on Microsoft's new mobile operating system.

This group of on-the-fencers cares more about hardware and software capability than brand name. If that's you, you're in luck -- there are no fewer than four smartphones preparing to make their splashy entrance and attempt to win you over.

These are rumored details so far, and even though most of these phones will launch in the next two weeks, they might not actually appear on shelves for a few days or weeks later. Also, we're not sure in which countries they'll be available, or for how much.

Apple's iPhone 6S isn't the only phone in town.
